  • How to pass encrypted command to ffmpeg from Windows 10 ?

    25 juillet 2019, par gaamaa

    While we pass commandline to ffmpeg and run it from Windows, others could see those commandline from taskmanager.
    Sometimes the url and password are secret which to be hidden from others.
    How to overcome this ?

    I don’t know ffmpeg coders thought about it and done something for this already.
    If I know C++ or relevant coding, I could add a custom decryption code block inside ffmpeg and use my encryption application to pass the encrypted command line.
    I don’t even know how to compile ffmpeg because its a nightmare even for professionals. (Why so complicated steps to simple compilation of an exe ?)

    Usual command line :

    ffmpeg -i MySource -codec:v h264_nvenc -s:v 1920x1080 -ac 2 -ar 48000 ... xyz ... -r 25 -f mpegts "udp://224.2.2.1:1234?pkt_size=1316"

  • configure : Remove carriage return ('\r') in Windows CC_IDENT

    31 janvier 2018, par Xiaohan Wang
    configure : Remove carriage return ('\r') in Windows CC_IDENT

    Currently the Windows CC_IDENT is ended with '\r\n'. "head -n1" will not
    
remove the '\r' and this is causing building error in Chromium.
    

    This CL adds "tr -d '\r'" to remove '\r' in the CC_IDENT string. Since in
    
most cases '\r' only appears at the end of a string/line, this should
    
work in most cases.
    

    See example :
    

    printf "hello\r\nworld\r\n" | head -n1 | hd
    
00000000  68 65 6c 6c 6f 0d 0a                              |hello..|
    

    printf "hello\r\nworld\r\n" | head -n1 | tr -d '\r' | hd
    
00000000  68 65 6c 6c 6f 0a                                 |hello.|
